Abstract: ABSTRACT OF THE DISCLOSURE      A line selector circuit for a television receiver identifies a predetermined horizontal line.  The line to be identified desirably occurs during the vertical blanking interval subsequent to he vertical sync interval contained therein.  A line of particular current interest is line 19 which contains reference information which can be used for automatic control of the receiver.  The pre-determined line is identified through the generation of a timing period which is initiated by a sync pulse synthe-sized by the summation of horizontal and vertical rate in-formation.  The timing period is terminated by horizontal sync information at the beginning of the predetermined line. The timing period is generate by a one-shot multivibrator having a first threshold circuit responsive to the synthe-sized sync pulse designed to initiate the timing period the same line in the vertical sync interval of either field.  The timing period is terminated prior to the natural delay of the one-shot when the amplitude of the timing wave-form of the one-shot which determines the natural delay of the one-shot is modified by added horizontal sync pulses to trip a second threshold circuit in the one-shot. The natural constant and the amplitude of the horizontal sync pulses are set so that the horizontal sync pulse at the beginning of the predetermined line will terminate the timing period.

Abstract: ABSTRACT        A skeletonized, adjustable, high-rise scaffold assembly employs stacked sections, each made-up of a pair of opposed end frames or panels.  The end frames of cooperating upper and lower sections are each provided with a pair of main or outer, supporting side legs and retained latching pin means for vertically adjustably connecting the sections together.  Side legs of each end frame have a pin connector extending inwardly within a plane of the frame to removably receive ends of cross brace members that are mounted to extend from an end frame of one section diagonally across in a connected relation with an opposed end frame of the other section.  The cross brace members have spaced-apart latching hole portions at at least one of their ends to enable a selection of a proper hole portion that is related to or compatible with an up or down adjustment of the frames of an upper section with respect to frames of a cooperating lower section.  In one embodiment, the section bracing connections are made between inner or secondary leg members of the opposed frames, and in another embodiment, the connections are between main or outer leg members of the opposed frames.

Abstract: ABSTRACT OF THE DISCLOSURE   A process for removing water from an aqueous solution.   A hydrate forming fluid is contacted with an aqueous solution at a temperature below the maximum temperature at which said hydrate forming fluid forms a solid hydrate in the presence of said solution and at a temperature at which the amount of solute present in the aqueous solution originally, exceeds its solubility in any solution remaining after hydrate formation so as to form a magma comprising solid hydrate, any unreacted hydrate forming fluid and any unreacted aqueous solution.  The hydrate forming fluid and at least part of the water constituent of the solid hydrate are separated from the solute by fractional sublimation and/or elution to produce a substantially hydrate forming fluid-free product comprising said solute and any remaining water.

Abstract: Abstract of the Disclosure Novel products can be prepared by reaction of monohydrazide and/or polyhydrazides, in particular dihydrazides, with mono-, d or, poly-acrylyl compounds.  The reactants can be chosen such th? the resulting polymers are strictly linear as in the case of re-action of a monohydrazide with a diacrylyl compound as follows:                    wherein each (O) is a carbonyl oxygen, n is a positive integer, each R is hydrogen or a monovalent group, and each Q is an organic group, R and Q being free of functions which would interfere with the desired reaction at 80°C.  Various degrees of crosslinking ca? be achieved by reacting monohydrazides with components containing an average of more than two acrylate double bonds per molecule or by reacting di-hydrazides with di- or poly-acrylyl compounds.     Fumaric, maleic and itaconic esters and acid esters add to hydrazides in a similar fashion as acrylates, the aliphatic double bond being similarly activated by the carbonyl group.  However, methacrylates are totally inert to hydrazide at 80°C.      These reaction products of polymers are useful as exterior protective and decorative coating materials for bonderized steel and the like.  Their impact resistance can be improved by reaction with toughening agents.

The top of the hood is provided with a central elongate hollow neck which projects upwardly into a longitudinally slotted exhaust duct paralleling the battery of ovens.  The slot in the duct has a pair of parallel extending flexible sealing strips which are biased toward sealing engage-ment with each other across the slot and which separate to seal on the neck of the hood as it slides longitudinally along the duct.  Selective communication is thus provided for flow of fumes, gas, smoke, particulates, etc. from the hood into the exhaust duct from the oven being pushed.

Abstract: ABSTRACT OF THE DISCLOSURE           A decoded PAM input signal is coupled through a first polarity switch (which for one polarity of a polarity signal is closed) to the positive input line of a differential operational amplifier and through the series combination of a second polarity switch (which is open for the one polarity) and an input resistor to the negative input line of the differential amplifier.  The positive input line is resistively connected to ground through a first bias resistor and is also connected to ground through the series combination of a second bias resistor and a third polarity switch which is also open for the one polarity.  A feedback resistor is connected between the output line and the negative input line of the amplifier.  By proper selection of resistances, this circuit provides a prescribed amplification of an input signal and changes its polarity as a function of a digital polarity signal that is applied to the switches, the circuit providing no change in output signal for a change in polarity signal when the input signal is zero amplitude.
